Since 1991 this Yosemite outfitter has eschewed the Sierra Nevada's more popular routes in favor of backpacking and hiking trips through lesser-known areas, such as the Ansel Adams Wilderness. When its guides do enter more touristy locales, like Mount Whitney, for instance, it's only after spending a bulk of their time traversing the Sierra backcountry.
